3 Claims.

This invention relates to ilushtype register frames, and also relates to the form of warm air registers for which there has been a considerable trade demand during the past few years. In

l such register arrangements the plaster of the wall or ceiling comes flush with the outside edge of the register proper, and trouble has arisen with these ilushtype registers for the reason that when the frame is fastened to the lath and plaster the plaster will break away because there is nothing provided to hold it from becoming detached along the edges. This invention has for its object the improvement of ushtype wall and ceiling frames for registers, ventilators, doors, etc., or for any location where it is desired to plaster the frame in ilush. This invention is not limited to the exact formation herein illustrated wherein the preferred construction is provided with corner strips, but it may be applied equally to any register frame. In some registers the frame is made of cast metal and relatively thick, and the openwork plate is sunk in and ilush with the upper surface of the frame.

The construction and disposition of the parts of this invention are illustrated in the accompanying drawing, of which Fig. 1 represents a front or top View of a frame showing all parts assembled in accordance with this invention.

Fig. 2 is a View of the rear side of the upper right hand corner of the parts set out in Fig. 1.

Fig. 3 is a sectional view taken on the broken line 3-3 of the lower part of Fig. 1.

Fig. 4 is a sectional view taken on the broken line 4--4 of Fig. 1.

Fig. 5 is a sectional view taken on the broken line 5-5 of Fig. 1.

Throughout the drawing and description the same` number is employed to refer to the same part.

Considering the drawing, the longer side member 1 has the downwardly extending portion or flange 2, and the like member 3 has a similar extension 4. The shorter upper frame member 5 in Fig. 1 has the downwardly extending portion 6 similar to the corresponding portions of the longer members, and the lower shorter member '7 has the downward portion 8 at right angles with the at top portion as shown in Fig. 3.

To hold the frame members together, the end 9 of the downwardly extending portion 4 of the side member 3 is turned over the downwardly extending portion 6 of the shorter frame member 5, as illustrated in Fig. 2, and those parts are spot welded together. The construction is the same at each corner and the frame members are thus secured together. Any other manner of securing the members may be used if desired.

Upon the flat upper surfaces of the combined frame members are placed angle iron pieces 10, 11, 12 and 13, and it will be noted that the lower nat sides of the pieces 10 and 11 extend inwardly to the open interior of the frame, while the like bottom flat sides of the pieces 12 and 13 extend outwardly as shown in Fig. 1. Those pieces, termed corner strips, may be electrically Welded upon the frame members, or suitably attached in any other chosen manner. They form a raised enclosure for a register plate, and are provided with the screws 14 at the inner corners of the enclosure by which the register plate 15, of any selected design may be removably connected.

Considering Fig. 4 it will be noted that the flat top of the side member 4 has struck up therefrom an integral projecting tongue 16, and each of the frame members is provided with such tongues spaced apart as\illustrated in Fig. 1. This invention is not limited to any number or form of projecting tongues 16, or to the spaces between them. In Fig. 3 it will be observed that the projecting tongue 17 extends over the bottom flat portion of the corner strip 13, and usually all the projections point towards the interior of the frame.

In addition to the tongues or lugs 16 the frame members are provided with screw holes 18 by which the frame may be secured to the usual lathing or other support 19, as illustrated in Fig. 5, and it will be seen in this Fig. 5 that the plaster` 20 is engaged and held by the tongue over and beneath which the plaster is applied. The plastering is flush with the corner strips 10, l1, 12 and 13 and with the register plate, and the edge portion of the plastering is positively held in place and under ordinary circumstances will not crack or become detached and break causing an unsightly appearance.

Having now described this invention and the manner of its use, I claim:A

l. A ushtype register frame, comprising frame members secured together, the said frame members having secured thereon angle iron pieces forming a raised enclosure for a register plate, means within said enclosure for securing a register plate, the said frame members having raised projecting tongues spaced apart and adapted to engage and hold plaster lush with the said enclosure and plate therein.

2. A llushtype register frame, comprising frame members secured together, the said frame 3. A flushtype register frame having a register plate secured thereon, an enclosure for said plate having horizontal flat sides, the said frame being provided with projecting tongues spaced apart and arranged to engage and hold plaster flush with a register plate carried by said frame, and a plurality of said tongues being also adapted to engage the fiat sides of said enclosure.
